Effect of Nonlinear Thermal Radiation on MHD Boundary Layer Flow and Melting Heat Transfer of Micro-Polar Fluid over a Stretching Surface with Fluid Particles Suspension

A comprehensive numerical study is conducted to investigate effect of nonlinear thermal radiation on MHD boundary layer flow and melting heat transfer of micro polar fluid over a stretching surface with fluid particles suspension. Using suitable transformations, the governing equations of the problem are transformed in to a set of coupled nonlinear ordinary differential equations and then they are solved numerically using the Runge–Kutta–Fehlberg-45 method with the help of shooting technique. Authentication of the current method is proved by having compared with established results with limiting solution. The impact of the various stimulating parameters on the flow and heat transfer is analyzed and deliberated through plotted graphs in detail. We found that the velocity, angular velocity and temperature fields increase with an increase in the melting process of the stretching sheet. Also it is visualize that the shear stress factor is lower for micro polar fluids as compared to Newtonian fluids, which may be beneficial in flow and heat control of polymeric processing.

Impact of ohmic heating on MHD mixed convection flow of Casson fluid by considering Cross diffusion effect

Abstract Present communication aims to discuss the impact of viscous dissipation on MHD flow, heat and mass transfer of Casson fluid over a plate by considering mixed convection. Nonlinear partial differential systems are reduced to the ordinary ones through transformation procedure. The modelled nonlinear systems are computed implementing RKF-45 scheme. Convergent solutions for velocity and temperature and concentration fields are given diagrammatically. The obtained results are compared with published literatures and reasonable agreement is found. It is found that, temperature profile increases by increasing values of Dufour parameter, whereas on opposite trend is observed in concentration profile for increasing values Soret parameter.

Impact of Chemical Reaction on MHD 3D Flow of a Nanofluid Containing Gyrotactic Microorganism in the Presence of Uniform Heat Source/Sink

Abstract The purpose of current study is to deliberate the effect of chemical reaction on 3D flow and heat transfer of an MHD nanofluid in the vicinity of plate containing gyrotactic microorganism over a elastic surface. Influence of uniform heat source/sink on temparature transfer has been considerd. The governing standard nonlinear system of equalities is resolved numerically via Runge-Kuttau2009 method ofu2009 45th order based shooting scheme. Role of substantial parameters on flow fields as well as on the, heat, mass and microorganism transportation rates are determined and discussed through ploted graphs.
